Step-by-step explanation:
Osman and the Ghazi
Osman was the founder of the Ottoman Empire and regarded himself and his followers as ghazis, which were warriors fighting to expand and protect the borders and influence of Islam. This was a significant part of the Ottoman Turkish identity that promoted Islamic values and aimed for a strong military presence in the region. Osman and his followers desired to become ghazis as it was seen as a religious and martial honor to fight for Islam, especially against the declining Byzantine Empire. Their efforts eventually led to the conquest of Constantinople and the growth of the Ottoman Empire, which became a prominent Islamic state with significant cultural, economic, and geopolitical influence for centuries.
